SLP Harmonic Balancer/Underdrive Pulley - 1997-09 Corvette (LS1, LS2, LS6, LS3)
SLP's 25% underdrive balancer for the LS1/LS6/LS2/LS3 Corvette and 2008-09 L76 Pontiac G8 and 2009 GXP incorporates a number of high-quality features you won't find on any other aftermarket unit. Chief among them are a pair of extra-tall belt-retention walls that eliminate the belt-slippage issues common to other balancers. Gains of up to 10 horsepower can be expected. Other unique design strengths include 100% steel construction (other brands use steel and aluminum), integral timing marks, and built-in puller-mounting threads. Includes a new balancer bolt and detailed installation instructions.
